The gauge below Sabil is a length of steel bolted to a pre-Upheaval concrete footing in the side channel, and Nadia Sabti reads it at first light because that is when the water sits flattest. She does not write the number down. She has never written it down. She says it once, out loud, to whoever is standing at the first gate, and by the time she has walked back up the bank the whole upper ladder knows what kind of day it is.
Sabil is about 2,400 people on a side channel of the Euphrates, in the stretch of the Mesopotamian black zone that appears on faction maps as an absence. Seven gates step water off the channel into the plots. Everyone calls it the ladder. It was built over twelve years by people who were not engineers, out of salvage and pre-Upheaval irrigation remnants, to hold a living out of a river running at less than a quarter of what it used to run. It worked. That is the part I could not get anyone upstream to sit with. For twelve years it worked.
There is a mark filed into the steel of the gauge a little under the 0.6, cut by somebody's grandfather with a triangular file. It is the level below which the top three plots of the ladder cannot be reached. It is not a warning. It is closer to a property line.
In March the water went under the mark and stayed there. Sabti measured the shortfall the way Sabil measures everything, in gate hours and channel width and a wristwatch, and arrived at forty-one cubic meters a day. I want to be careful about what I am claiming for that figure. It came off a filed notch and a woman standing in the cold at 5 a.m. It was also, as far as anyone has been able to show me since, correct.
The Sons of the Serpent had been in Sabil for eleven years, quiet, providing what security and logistics a river town needs and taking the legitimacy in exchange. In April they stopped coming to the Thursday meeting. Nobody in Sabil would tell me more than that, and I stopped asking on the second evening, because the way they were not saying it was already the answer. A town below the mark has nothing left over to hide anyone in.
Captain Sami Ghazal came down from Basra in May.
He is thirty-four, civil affairs, PCU Northern Command, which means he works for General Fatimah al-Rashidi and knows it in the way people know who signs a thing. He is precise and he does not oversell. He brought a tanker on a low loader, a folding table, and household registration forms, and when the gate committee asked him what the forms were for he told them, in order, without decorating any of it: allocation, curfew, movement on the river, medical.
The schedule he handed across the table lists Sabil's daily delivery at forty-one cubic meters.
Not forty. Not fifty, which is the number you bring when you want to be seen being generous. Forty-one. Sabti had not given that number to anyone outside the ladder, because there was nobody outside the ladder to give it to. There is one other gauge on that reach of the river. It is two hundred kilometers upstream, at the dam.
I put this to Ghazal twice, on separate days, as plainly as I could manage. Both times he answered the question I had actually asked, which is its own kind of information. He said the allocation was calculated from headwaters flow data held at Northern Command. He said it the way a man says that the arithmetic was done properly, and I believe he thinks it was. Somebody in Basra knew the size of the hole before Sabil finished measuring it.
The town signed. There was a meeting and there was an argument and it lasted most of a night, and then 2,400 names went onto the forms, because the alternative was the top three plots and then the next three. The forms have a household count, ages, and a line for genomic classification, for medical allocation. Three families in Sabil are gene-forged. They are on the list now with a box filled in. Movement on the river takes a card. Card 0114 belongs to Yusuf Sabti, who is nineteen and works four days a week on the PCU pump platform, which is the only wage in the town. His mother did not say one word to me about that. She did tell me, with nobody asking, what it costs to replace a lost card.
I do not think Ghazal is the cruelty here. He would have run the same table on a river the PCU had never touched, and run it decently. That is the difficulty with filing this piece at all. Every person I met in Sabil in the first week of the delivery schedule was working in good faith inside an arrangement that only makes sense if you already know what happened at the headwaters, and the people who know that are not in Sabil.
In June the civil affairs team repainted the gauge. Marine grade, correct numbering, a better job than the one it replaced, and it will outlast most of what is standing on that bank. Sabti walked me down to it on my last morning and put my hand on the steel below the 0.6. The notch is still there. It has not worn a millimeter. Under two coats of good paint you can feel the edges of it with a thumb and you cannot see it at all, not from the bank, not from the first gate, not from anywhere in Sabil where a person would normally be standing.
She still reads the gauge at first light. There is a schedule now and the number does not change anything, and she says it out loud anyway, and the upper ladder still stops what it is doing to hear her.
